The Taihu Lake is situated in the centre of the dish-like lowlying land south of the Changjiang River, which was resulted from the two dynamic factors, the long-term ground depression at a rate of 0.4 mm/a, calculated from the archaeological data, and the rise of the postglacial sea level that was responsible for the formation of the high coastal plain on the east margin of the dish-like low-lying land.
本文从沉积学、地层学、地貌学、考古学和历史地理学角度,综合分析了太湖的成因和演变。认为地壳沉降与海面上升是构成江南碟形洼地的内外动力,为太湖的形成奠定了基础。全新世海侵最盛时,太湖海湾水深潮急、泻湖、滨海沼泽围绕海湾分布。随南部湾口沙嘴封堵,海湾趋于消失,陆地扩大,遗址增多。3700a来,海面回升,湖面逐渐扩展,形成现代太湖。

Based on the study of rock textures and structures, and stable isotopes of dolomite and S isotope of barite interlayers within the cap dolomite outcropped in the Miaohe area in the Three Gorge, it is testified that the stable isotopes show a strong negative excursion, and the isotopes of sulfur show a significant positive excursion, which is similar to the reported data of authigenic barites formed in a modern seafloor gas hydrate environment. Therefore, it can be concluded that the cap dolomite was most likely formed in a special environment under which a huge gas hydrate dissociated with the breakup of "Snow Earth" in later Neoproterozoic.
通过对湖北三峡庙河地区出露的&盖帽&白云岩的野外地质构造、碳-氧稳定同位素和重晶石夹层的硫稳定同位素特征的研究,发现除了明显的碳稳定同位素的负偏移之外,重晶石的硫同位素值表现出明显的正偏移,其数值可与现代海底甲烷喷气孔附近的自生重晶石矿物的同位素组成相对比,进而认为&盖帽&白云岩的成因是末元古代&雪球&事件之后天然气水合物的释放与全球环境突变背景下的沉积产物。

Based on the theory of two-phase fluids dynamics, the general governing equation is established, which is applied to the fields of seepage, consolidation and deposit. For the first time, the mechanics properties of the soil affected by seepage are studied by the means of experiment. The problems of the modified indexes of mechanics and constitutive relation are solved due to the formulations obtained of mechanics parameter under seepage condition. Applied fuzzy theory and modern project design method, the fuzzy probability model for stability analysis is stetted up; Considered variation of mechanics parameter and curtain effect, the deformation patterns of deep execution are systematically analyzed.
